Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU63328
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-0562
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the memcpy() function within TIFFReadDirectory() in tif_dirread.c. A remote attacker can trick victim to open specially crafted TIFF file and perform a denial of service (DoS) attack.

3) Out-of-bounds read
EUVDB-ID: #VU63795
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary condition in the _TIFFmemcpy() function in tif_unix.c in certain situations involving a custom tag and 0x0200 as the second word of the DE field. A remote attacker can pass a specially crafted file and perform a denial of service attack.

EUVDB-ID: #VU63329
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-0891
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing TIFF file in ExtractImageSection() function in tiffcrop.c. A remote attacker can create a specially crafted TIFF file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
